Hi all,

xsm policy which is used for controlling the hypercall(communication)
between vm's.

and i also i find that there is 'svirt' which is used for isolating vm's.
I want to know that is svirt will work in xen.??  because i find svirt is
for KVM.

Anybody clear me these things.


Regards,
cooldharma06.

The XSM policy in 4.3 has a type for isolating VMs called isolated_domU_t
which prevents a domain from directly communicating with other domains.
However, indirect communication in Xen can be done using Xenstore, so
a pair of cooperating VMs can still communicate. This may or may not be an
issue for you, depending on what you want from svirt.
